Research: Neurophysiology of the cingulate cortex; in particular, the role of cingulate cortex in pain sensation. Cingulate cortex is an important region of the pain system which provides the emotional, affective component of pain sensation ï¿½ the unpleasantness of pain. My research has used a combination of neurophysiological and neuroanatomical techniques to identify the distribution of nociceptive neurons within the subareas of cingulate cortex and to define their physiological properties. We have investigated pathways through which pain information is transmitted and are currently contrasting the effects of somatic and visceral noxious stimulation on cingulate neuron activity. Additional areas of interest: Plasticity of cortex, alterations of receptive fields following loss of sensory input; dopamine systems, neurophysiology and anatomy of striatal nuclei.
